I have installed Vista OEM 64-bit version of Ultimate and build 7000. I have tested this on both machines. I wanted to press Control-Alt-Del when I needed to log in. No big deal to do this via control userpasswords2 in Vista and Windows 7. I then rebooted and had to press Ctrl-ALT-Del to log in. Then I wanted to do one more thing. I wanted to join a domain. That is ok to do. ( I have a Windows 2003 domain). But then I decided not to joind a domain. So I re-joined the workgroup. No big deal. But why did the re-join to workgroup kill the press Ctrl-Alt-Del screen? thanks

Hi DavidIt sounds like the most likely cause would be when you re-joined the system to the Workgroup, all of the default settings were returned to the defaults which would include disabling the CTRL+ALT+DEL option. Hope this helps. Thank You for testing Windows 7 Beta Ronnie Vernon MVP

I disagree. If I sent Windows to force and Ctrl-ALT-Del usage on logon and that is the default behavior prior to joing a domain, then why does it change? It doesn't make sense.

Hi David, Yes, its a suggestion. Windows should backup your personal setting before joining domain. After re-joining to workgroup, Windows should restore personal setting on the computer. I will report it to our internal team. Thanks.
